Overview of residential proxies services By penetrating Proxy Residential services, the author was able to effectively collect information about the pool of residential proxies. Specifically, during the penetration process, the author launches multiple Residential Proxies to capture data from different locations and accounts each day and runs them at different times of the day to reveal as much as possible about the state of the dynamic Residential Proxies pool. Ultimately, the author captured 6 million residential proxies by sending 62 million requests. Due to the volatility of the network environment (especially in mobile networks), this number should be considered as an upper limit for the number of residential proxies hosts. The table shows the distribution of each residential proxy service provider across different network blocks and ASes, with ProxyLite having the largest pool of rotating residential proxies, followed by Proxies Online and ProxyRack. When analyzing the countries, ASNs, and ISPs with the largest number of residential proxies, the author observes a clear long-tail distribution phenomenon. A handful of countries, ASNs and ISPs contribute the majority of residential proxies. For example, although ProxyLite is headquartered in Hong Kong, China, the majority of its residential proxies come from Europe, which may be related to the web censorship in that country. It is worth noting that ProxyLite claims to have 72M+ proxies, a huge amount. Residential Proxies Infrastructure and Services While researching the infrastructure of residential proxies services, the author found a series of hidden back-end gateways between front-end gateways and residential proxies. These back-end gateways were found in the connections between the proxies' gateways and the residential proxies. I will explain what follows: a series of hidden back-end servers exist between the front-end gateway and the residential proxies. From the perspective of the residential proxies, these servers can be seen as gateways, hence the author refers to them as back-end (hidden) gateways. The author's traffic logs, PUP traffic, and passive DNS datasets record these connections. The author observes that prior to traffic relaying, PUP-hosted residential proxies typically communicate with hidden back-end gateways rather than interacting directly with front-end gateways. The author further analyzed the PassiveDNS data and found that these hidden back-end gateways share a set of IPs with the front-end gateway, strongly suggesting that they belong to the same network architecture. Specifically, using ProxyLite as an example, the author observed that the PUP hosting residential proxies always communicate with the back-end servers rather than the front-end gateways before relaying the infiltration traffic. And some of its subdomains act as back-end gateways that communicate with the residential proxies, while all front-end gateways are clean. This shows that by separating the different components in this way, it makes the whole ecosystem more robust. The author also investigates the sharing relationship between different residential proxies service providers. By calculating the crossover rate and setting strict criteria, the author found multiple residential proxies addresses shared across service providers that may have a partnership or some of these brands actually belong to the same company. In a further analysis of the residential proxies infrastructure, the author discovered through port scanning that these front-end and back-end gateways tend to have a large number of contiguous ports open. The presence of these ports not only allowed the author to identify the infrastructure of residential proxies services, but may also provide clues to potential detection and defense measures. Conclusion. The complexity of the residential proxies ecosystem is manifested on multiple levels, including cooperation between service providers, distribution of infrastructure, and involvement of IoT devices. By delving into the infrastructure and operations of residential proxies services, the author has revealed the true state of their network. the transparency and trustworthiness of ProxyLite's services can be examined as a major player in the field. In future research, it will be important to explore how to effectively detect these networks of proxies.

In today's era of rapid digitalization, Proxy Residential have become an important tool for network security and traffic management.

How residential proxies work Residential Proxies are a service that forwards user requests through residential addresses. These residential IPs are assigned by real ISPs, so residential proxies make it appear as if the user's web behavior is coming from a real home user, rather than a data center or other commercial service. The key to residential proxies is their ability to provide a more trusted and stable pool of addresses. This approach not only helps to bypass restrictions on certain websites, but also avoids being flagged or blocked for using commercial proxies. This has a wide range of applications for conducting global marketing, automating tasks, and data crawling. Security Challenges of Residential Proxies Despite the many conveniences that residential proxies offer, they also face a number of security issues. Our research has found that residential proxies can become an intermediary platform for cyber-attacks and malicious activities. To address these issues, future work needs to focus on effectively detecting and preventing misuse of residential proxies services. How to detect residential proxies services? Detection of residential proxies services can be divided into three main parts: website detection, front-end gateway detection, and back-end gateway detection. 1. Website Detection Residential proxies' websites usually contain specific keywords, such as “residential IP”, “HTTP/HTTPS/SOCKS” and so on. These keywords can be quickly scanned and identified through search engines or automated tools. This method provides a convenient way to identify potential proxies. 2. Front-end gateway detection Front-end gateways tend to use the same domain names or addresses as residential proxies sites and tend to open a large number of TCP ports to serve different proxy needs. These features make front-end gateway detection more intuitive. 3. Backend Gateway Detection Back-end gateways are usually detected by a large number of global DNS queries and the characteristic of open ports. Combined with these features, data analytics can be utilized to discover hidden proxies networks. Mitigating the Residential Proxies Abuse Problem Detection is only the first step in solving the residential proxies abuse problem. What is more important is how to develop an effective mitigation strategy. We need to identify patterns of abusive behavior through in-depth data analysis and develop targeted solutions. Meanwhile, as more and more residential proxies are used for commercial purposes, the detection and mitigation of abusive behaviors will become an important direction for future research. By using machine learning techniques, we can automatically identify and flag potentially malicious proxies services, thereby improving overall network security. Future Prospects of Residential Proxies As Internet technology continues to advance, residential proxies services are also evolving rapidly. In the future, residential proxies will play an even more important role in areas such as cybersecurity, data analytics, and automated tasks. However, as these services expand, we also need to face more complex security challenges. To ensure the healthy growth of residential proxies services, future research and development needs to focus on the following areas: 1. Increasing the transparency of proxies services By increasing the transparency of the service, users and service providers can better understand how proxies are being used. This can help prevent abusive behavior and ensure compliance of proxies services. 2. Develop automated detection tools Using artificial intelligence and machine learning technologies, automated detection tools can effectively identify and stop abusive behavior. This not only improves the efficiency of detection, but also reduces the error of human intervention. 3. Enhance international cooperation Abusive behaviors of residential proxies are usually global in nature, so international cooperation is crucial in solving these problems. Countries should work together to develop cybersecurity standards and strengthen the fight against transnational cybercrime. Conclusion As an important cyber tool, residential proxies play an important role in enhancing security. However, it is also challenged by abuse and security issues. With effective detection and defense measures, we can reduce the risk of residential proxies being misused and ensure that they play their proper role in legitimate business activities. As technology continues to advance, the future of residential proxies will be full of opportunities, but it will also require us to keep an eye on the security risks they may pose. By optimizing detection methods, strengthening international cooperation and enhancing transparency, we can pave the way for a healthy development of residential proxies services. Residential proxies will play an integral role in the future of a safer and more efficient online world.
